Splitting Your Model Railway Layout - tams elektronik B-3 Manual

B-3
Short-circuit protection
The booster B-3 has a short-circuit protection. In case the power
consumption in the connected track section exceeds 2,5 A, the booster
indicates a short circuit to the central unit. The central unit then switches
off the track voltage. This prevents damage to the booster, vehicles and /
or tracks.
Operation with DCC central units
The booster amplifies the track signal completely symmetrically. This
allows the ABC-braking method to be used in DCC-controlled layouts.
The DCC-input of the booster B-3 is isolated through an opto-coupler.

4. Splitting your model railway layout

Split your model railway layout in several track sections electrically
isolating them from each other. Every section has to be supplied by a
booster of its' own. In each section a maximum of three to five
locomotives should run at the same time. The following divisions are
useful:
§
station
§
engine sheds
§
the main line (if necessary in several sections)
§
the branch lines (if necessary in several sections)
Make sure that section borders are not crossed that often. Cut both
rails and with 3-rail systems the middle conductor as well at the
borders.
!
Please note:
With some boosters cutting the middle conductor of 3-rail systems at
the borders of the booster sections is sufficient. This is different when
using the B-3! Here you have to cut the rails as well, or else the booster
may be damaged through overload.
